Properties Preserved by Groupoid Equivalence
Daniel W. van Wyk, Dana P. Williams
We show that groupoid equivalence preserves a number of groupoid properties such as properness or the property of being topologically principal.
The Primitive Ideal Space of Groupoid C*-Algebras for Groupoids with Abelian Isotropy
Daniel W. van Wyk, Dana P. Williams
We study the topology of the primitive ideal space of groupoid C*-algebras for groupoids with abelian isotropy. Our results include the known results for action groupoids with abel…
The orbit spaces of groupoids whose -algebras are CCR
Daniel W van Wyk
Let G be second countable locally compact Hausdorff groupoid with a continuous Haar system. We remove the assumption of amenability in a theorem of Clark about groupoids whose $C^*…
